AUTOMATIC LIGHT-SWITCH.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application tiled February 23, 1907. Serial No. 358,839-

To all whom it may concern:

The contact members l1 and t2 are connected to the lie it known that l,Ilnxnv Enwanns Kixo. a citi- I terminals of a lighting circuit ltincluding a battery Zen of the lfnitcd States. residing at liunkie. inthe parish of Avo velles and State ot' Louisiana. ha e iuvented a newand usel'ul Automatic Lightmwitcn, which the following is aspecification.

This invention relates to automatic alarms and more particularly to anelectric switch especially designed tor use in connection with an alarmclock tor automatically closing a lighting circuit at prea eterminedintervals.

The object ot the invention is to provide a switch including 'a pair otcontact; members one ot which is arranged in the path of movement of thehammer ot an alarm clock or similar device so that when the alarmsounded the hammer will move the adjacent contact to circuit closingposition and thus light the lamps.

A still further object ot the invent ion to generally I improve thisclass ot' devices so as to increase their utility. durabilit andetliciencv.

With these and other objects in view the invention consists in theconstruction and novel combinai ion and arrangement, of partshereinatter tully described. and illustrated in the accompanvingdrawings, it being understood that various hanges in term. proportionsand minor details ot' construct ion may be resorted to within the scopeof the appendet'l claims.

in the accompanying drawings forming a part of this speciticatimt:Figure l a front elevation of an electric switch constructed inaccordanc with my invention showing the movable contact, in position tobe engaged by the hammer of an alarm clock. a rear elevation ot thecasing or housing showing the relative position of the contact members.Fig. I} is a longitudinal sectional view taken on the line S- 3 of Fig.2. Fig. t is a transverse sectional view taken on the line 4-4 of Fig.2.

Similar numerals of reference indicate corresponding parts in all ol thefigures ot the drawings.

The device comprises a casing or housing 5 designed [or attachment to awall or other suitable support and provided with vertically disposedlugs 6 having perforations tormed therein for the reception of screws orsimilar tastcning devices 7 whereby the casing may be convenientlysupported on the wall.

The casing 5 is provided with a pivoted cover or closure 8 having aspring catch or similar fastening dcvice 9 secured thereto and adaptedto engage the top l of the casing for locking the cover in closedposition. The opposite end walls of the casing are provided with alinedopenings in which are seated bearing collars or .1

sleeves 10 adapted to receive a pair of contact mem bers 1] and 12,there being bushings l3 formed of rub- 115 and one or more incamlescent,lamps to. tact member it is relatively stationary while the member .12is mounted tor longitudinal movement within the casing or housing and isprovided with a terminal head 17 which extends in the path ot movementof the vibrating hammer 18 of an ordinary alarm clock, indicated at it).

The head i7 is cccentrieal1y mounted on the adjacent end ot' the movablecontact, l2 and is preferably provided wlili a. disk 20 tormtd oi rubberor other suitable yiclt'lable material adapted to receive the impact ofthe hammer 1S.

Secured to the inner wall of the cover or closure 8 is a strip ot metal3t having a laterally extending tlangc 22 dctining a pocket tor thereception ot an insulating block 225, the latter being prt-t'erablytermed of glass or other suitable material and having a convex tactadapted to bear against the curved or deflected end j) of the stationarycontact member l l.

The tree or inner end or" the movable contact member 12 is provided witha laterally extending lip 2t; adapted to engage the defl cted end 25 ofthe stationarv member it and thereby close the lighting circuit win-nthe contact 12 is moved longitudinally by engagement with the hammer 18ot' the alarm clock.

in operation the clock, is set to sound the alarm at any pre-determincdperiod and the movable contact l2 arranged in the path of movement ofthe hammer IS. as best shown in Fig. :1 of the drawing When the alarm issounded the hammer l8 will strike the head l7 ot' the movable contactand t'orce the latt r longitudinall in engagement with. the llattenedend ot' the stationary contact l'l tints autolmiticallv closing thecircuit and lighting the lamp or lamps. in order to extinguish the lampsit is merely necessary to exert a longitudinal pull on the head orlinger piece 17 when the contacts will be separated and the lightingcircuit broken. i

Attention is called to the tact that by having the instilatiug block 43t'ormed with a convex lace and the flattened end of the stationarycontact Ill bent to conform to the contour ol the lace ot' the block,the contact 12 when moved to circuit closing position will ma kc a wipecontact with the member it and thus insure a good electrical connectionbetween the two. it will also be observed that when the detlccted endofthe movable contact 12 engages the inclined end ol' the stationarycontact the end 20 ot the movable contact will be lore-ed outwardly thusexerting a sprin action on the stationary contact and serving as anadditional means l'or holding both contacts in circuit closing position.3y having the insulating block 23 arranged within the pocket and thelatter secured to the pivoted wall or closure-8 when said block becomesbroken or otherwise injured from rough usage or from any other cause-thesame may be he coni readily detached by moving the door or closure 8 toopen position and removing the block through the open end of the pocket,as will be readily understood.

From the foregoing description it is thought that the construction andoperation of the device will be readily understood by those skilled inthe art and further description thereof is deemed unnecessary.

Having thus described the invention What is claimed is:

1. An electrical switch including co-acting contacts one of which isprovided with a terminal head having a cush ioning member securedthereto, an energized circuit the terminals of which are secured to thecontacts, an insulating block bearing against and forming a support forthe adjacent end of one of the contacts, and an alarm clock having avibrating hammer adapted to engage a head of the adjacent contact formoving the latter to circuit closing position.

2.
